Unable to add variable values to DB using TryUpdateModel

Question

I have a variable which has values and I am trying to add to DB using TryUpdateModel and eventually it doesn't happen.

 

Getting below error message.

[HttpPost]
public ActionResult CreateAccount(FormCollection collection)
{
string msg = string.Empty;
try
{
var accountdetail = new AccountDetail();
TryUpdateModel(accountdetail);
AccountRepository userRepo = new AccountRepository();
if (userRepo.CreateUser(EntityHelper.InitializeUser(accountdetail, 0)))
return Json(new { Result = "Success", InfoMsg = msg });
else
msg = "Error returned";
}
catch (Exception ex)
{
msg = ex.Message;
}
return Json(new { Result = "Failed", InfoMsg = msg });
}

Error Message:
